The comprehensive guide to applied PR theory in the 21st century Public Relations Theory explores the central principles and theoretical components of public relations and their practical applications in actual situations. This informative text helps readers to understand the concepts, approaches, and perspectives of PR theory and learn development methods, implementation strategies, management techniques, and more. Chapters written by recognized experts on each topic provide readers with knowledge on how, when, and why appropriate theories are applied.
